Anthony Richardson, quarterback for the Indianapolis Colts, has received an initial injury diagnosis of a Grade 3 AC joint sprain. He is scheduled for an MRI to confirm the severity of the injury, but a Grade 3 sprain would likely require a recovery timetable of a month or more. There is a possibility that Richardson could be placed on injured reserve. If that happens, Garner Minshew will take over as the starting quarterback for the Colts.
